- Updated by O.Kleinecke in March/April 2015 to improve LP-NAND-Chip support.
- KNOWN ISSUES : TODO : Add (cleaner!?) OOB/ECC Support for LP-Devices.
- TODO : Add create/read BBT functions
- Investigate FTDI/Code based malwritten/malread bytes (byte mismatch for read/write after chip erase every 256/256+1/256+2 bytes)
